High Temperature Wire & Fire Resistant Cables/ 450/750 BVR Cable use for House or Building
Wire & Fire Resistant Cables Application
BVR wire is a kind of copper core PVC insulated soft wire, which is used in fixed wiring situations requiring softness. This product is suitable for fixed laying of power plant with rated AC voltage below and including 450/750V, such as home lighting. Fixed wiring can be used in indoor open application, conduit and other occasions. In order to facilitate the difference in the installation process, it can be divided into seven colors: red, yellow, blue, green, black, white and both. Because BVR is soft structure, its application scope is mostly in soft environment.
Wire & Fire Resistant Cables Installation
Open air, or in conduits, or trunking.

ZR-BVR cable(flame retardant cable) is the kind of cable with PVC insulation built mixed with fire prevention additive to make it have the capability of preventing or retarding flame spread during combustion.
NH-BVR cable(fire resistant cable) is the kind of cable built with a layer of mica tape. Even if the plastic skin is burnt out, refractory layer will help not cause short circuit. When wiring, cut off the refractory layer at the wire head.
LSZH,LSOH,LS0H,LSFH or OHLS BVR cable(Low smoke zero halogen cable)is cable with insulation or outer sheath built using low smoke zero halogen free material to help reduce toxic and corrosive gases produced during combustion.
Termite-proof BVR cable is the cable built with insulation or outer sheath mixed with a kind of materials to prevent termite biting the cable.
